How to chain multiple AJAX requests in sequence with jQuery's $.when()?

To chain multiple AJAX requests in sequence with jQuery's $.when() method, you can follow these steps:

Define your AJAX requests using the $.ajax() method or any other shorthand method ($.get(), $.post(), etc.).
Pass all the AJAX requests as arguments to the $.when() method, separated by commas.
Attach a .then() method to the $.when() method to handle the response of all the AJAX requests.

Here's an example of how your code may look:

$.when(
  $.ajax({
    url: '/first-url',
    method: 'GET'
  }),
  $.ajax({
    url: '/second-url',
    method: 'POST',
    data: { param1: 'value1', param2: 'value2' }
  }),
  $.ajax({
    url: '/third-url',
    method: 'GET'
  })
).then(function(response1, response2, response3){
  // Handle the response of first AJAX request
  console.log('Response 1:', response1[0]);

  // Handle the response of second AJAX request
  console.log('Response 2:', response2[0]);

  // Handle the response of third AJAX request
  console.log('Response 3:', response3[0]);
});

In this example, all three AJAX requests will be executed in sequence. The response of each request will be passed as an argument to the .then() method, and you can handle each response individually.
